WINDOW-SCREEN.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed May 21, 1908. Serial No. 434,077.

To all whom it may concern:

Be it known that I, PATRICK F. Down, a citizen of the United States,residing at Port- 1 land, in the county of Multnomah and State ofOregon, have invented certain new and useful Improvements in Window-Screcns; and I do declare the following to bc a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of i reference markedthereon, which form a part p of this specification.

My invention relates to window screens and has for its object to providea rolling window screen which can be easily ant quickly attached to awindow and which will effectually prevent the ingress of flies or otherinsects.

A further object of my invention is to provide a simple means forpreventing the ingress of flies or other insects between the window aneof the lower window and the sash of t e u per window.

A further o liject of my invention is to provide a rolling window screenwhich can be quickly and easily raised in order to allow free passagethrough the window, as is neces sar for washing windows or for passingarticles therethrou h.

With all these 0 jects in view my invention consists in the novelconstruction and arrangement of parts all of which will be first fullydescribed and afterward specifically pointed out in the appended claim.

Referring to the accompanying drawings: Figure 1 is an elevation of awindow showing my invention in operative position. Fi 2 is a verticallon itudinal sectional view ta on on line 22 of ig. 1. Fig. 3 is asimilar view showing rolling screen in raised position. Fig. 4 is anelevation of a window showin bottom sash lowered. Fig. 5 is an enlargesectional view of the upper portion of the bottom sash and the lowerportion of the u per sash. Fig. 6 is an enlarged sectional view showingthe uard and guide for the rollin screen, and ig. 7 is an enlargedsectiona view of the rolling screen showing bottom sash in a loweredposition.

Like numerals of reference indicate the same parts throughout theseveral figures in 1 having which 1 indicates a window, 2 the upper sashand 3 the lower sash.

4 indicates the rolling screen which, as

shown in Fig. 7, comprises a roller 5 sup ported on a guide 6 at eachend thereof, said roller 5 having a spring therein not shown normaltendency to rotate the roller 5 to wind the screen 4 thereon. A base 7is provided to which. the guides c are secured, said base 7 normallyresting on the window sill 8 clearly shown. The upper or free end of thescreen 4 is secured to the lower portion of the lower sash 8 by means ofa strip 9 or by any other convenient means and I provide a guard 10which is carried on the base 7, said guard being curved as shown in Fig.7 to protect the screen 4 and which prevents flies or other insects fromentering between the screen 4 and base 7.

Along each side of the lower sash 3 and vertically disposed as shown inFigs. 4 and 7 I provide a guiding strip 11, said guiding strip beingprovided with a longitudinal groove 12 as shown in Fig. 6, said groove12 accommodating the guides 6 which support the roller 5; and in orderto hold said guides in position within the groove 12 in order tomaintain the screen in its lowermost position as shown in Fig. 7 Iprovide a transverse pin 13 which enters the guiding strip 11 above theguides 6, thus preventing movement of the guides 6 within the grooves12.

Referring now to Fig. 5 it will be seen that under the lower portion ofthe upper sash 2 I provide a strip 14 carrying a brush 15 which brushextends inwardly beyond the sash 3 and engages the outer surface of thelower window pane 16 as clearly shown.

Having thus fully described the several parts of my invention itsoperation is as fol lows: In order to attach the screen to a window theguiding strips 11 are placed in position as shown in Fig. 4; the rollerand screen are passed down the grooves 12 until the base 7 rests uponthe window sill 8; the pins 13 are then passed through the guidingstrips 11 which securely hold the device in position shown in Fig. 7;the outer or free end of the screen is then secured to the lower portionof the bottom sash 3 in any convenient manner. The screen is then inposition for use, and when the sash is raised, as shown in Fig. 2, thescreen is unwound from the roller 5 which effectually closes the openingthrough the window, thus preventing access of flies or other inserts;and when the hottoin sash is in a lowered position the roller 5 winds upthe sereen as shown in Figs. 4 and 7. When the bottom sash is in apartially iaised position, as shown in Fig. 5, the brush 15 carried onthe upper sash prevents the ingress of llies or other inserts throughthe usual space between the lower window pane and the lower poi tion ofthe upper sash.

1t l'retpn-ntix' lltflHlltS necessary to remove a screen from the windowin order to wash the same or for the purpose ol' operating shutters orthe like and also for passing ohjeets throrgh the opening. in order toaeeonlplish this and to remote ohstluctions ol' the screen it is simplynecessary to remove the pin 12; llUlll each of the guiding stiir s H.The lower sash ean then he raised and the entire screen and roller willmore upwardly guided by the guide ship 1] to the position shown in Fig.3%. \vhen it is desired to replaee the sereen the bottom sash is loweredand the pins 13 inserted in proper position as shown in Fig. 7. By thisconstruction and arrangement the sereen ean he removed from the windowin a very short space of time as it simply requires the removal of thepins 13 in order to allow the entire screen and roller to he raised inposition shown in Fig. 3.

Having thus deseribed the several parts of my invention what I claim asnew and desire to secure 1) Letters Patent of the United States is;

A rolling screen ol the character described eolnprising a roller towhich one end of the sereen is seeured, a base, guide pieces thereon towhich guide pieces the roller is secured, a guard on said base, aguiding strip located on eaeh side edge ol'the lower sash and in theinner side of the same, said guiding strips being provided with groovesto receive the said guides supporting the said roller, and

lillilHS entering each of said guiding strips to hold the said guidepieees and roller in a lowered msition, the outer or free end ol saidrolling sereen being adapted to he seeiered to the lower portion of thehottoin sash.

in testimony whereof, I aflix my signature, in presenee of twowitnesses.
